Near the Passeig de Pujades entrance to Parc de la Ciutadella is the monumental cascada (waterfall). Created between 1875 and 1881 by Josep Fontserè with the help of an enthusiastic young Gaudí, it is a dramatic combination of statuary, rugged rocks, greenery and thundering water. All of it perfectly artificial! Nearby, hire a rowing boat to paddle about the small lake.
